My invention relates to weir plants, and more especially such, in which two sluices, i. e. a bottom sluice and an upper sluice are used.

The object of the present invention is to avoid in such weir plants certain well-known drawbacks found in weir-plants of that type.

In accordance with the invention, the front or upstream sluice, which may be either the upper or the lower sluice, comprises a front or damming wall having only a single main cross bar or beam extending rearwardly therefrom. In case the front sluice is the lower sluice the single main cross bar or beam extends rearwardly from the bottom thereof. If, on the other hand, the front sluice is the upper sluice, the single main cross bar or beam extends rearwardly from the top thereof. In either case, the single main cross bar or beam forms with the front or damming wall of the front sluice an acute angle, whereby the said front sluice is effectively resistant to torsional and bending forces to which it may be subjected. Moreover, the front or damming wall of the front sluice is provided at its rear, ad-

jacent to its lower or its upper free edge, as the case may be, with rollers which abut the front face of the front or damming wall of the rear sluice, whereby the front sluice, despite its V- shape or inverted V-shapein cross section, as

the case may be, is effectively held against If the front sluice is the lower sluice, the lower wall of the rear sluice has the same inclination to the front or damming wall of said rear sluice as the inclination of the main cross bar or beam of the front sluice to the front or damming wall of said front sluice. Similarly, if the front sluice is the upper sluice, the top wall of the rear sluice has the same inclination to the front or damming wall of said rear sluice as the inclination of the main cross bar or beam of the front sluice to the front or damming wall of said front sluice. Thus, in either case, when the front and rear sluices are moved together to their inoperative structure.

or closed positions relatively to each other, the rear sluice is compactly nested in the space behind the front or damming wall of the front sluice and the two sluices therefore are advantageously of minimum combined height. p 5 For a better understanding of my invention I will now describe the same more in detail with reference to the annexed drawings, in which, by way of illustration, I have diagrammatically shown three embodiments of the invention, and 10 in which Fig. 1 is an end View of the improved weir, the upper sluice being shown in its operative position; Fig. 2 is a similar view as Fig. 1 showing the upper sluice in its lowered position; Fig. 3 is a perspective view of the weir showing the upper sluice in its lowered position as in Fig. 2'. Figs. 4 and 5 are similar views as Figs. 1 and 2 respectively showing a modified construction. Figs. 6, 7 and 8 show a further modification. 20

Firstly, as shown in Figs. 1 and 2, the upper sluice which is of trapezoidal shape in section, comprises the vertical compression boom I, which, at the same time, constitutes the front or damming wall, the tension boom or rear wall 2, the top wall or web 3, constituting the back of the weir, and the bottom wall or web 4. At 5 are shown transverse members properly spaced apart for reinforcing and stifiening the sluice 80 The V-shaped bottom sluice shown in Figs. 1, 2 and 3 comprises the double-walled vertical leg 6 and the likewise double-walled upwardly inclined leg 1. These two legs form with each other an acute angle e. At 8 is shown the front 85 or damming wall of the bottom leg 6 of the sluice, which damming wall forms part of the compression boom 9, while at I0 is shown the tension boom closing the rear of the box-shaped structure of the upwardly inclined leg 1. At ll in Figs. 1 and 2 are shown V-shaped frame members which lying within the V-shaped box-like structure, do therefore, as distinguished from known constructions, not necessitate a separate place outside the main cross bar or beam comprised by the leg 1, while the V-shaped box structure of the bottom sluice consequently possesses great stiffness capable of withstanding torsional stresses. In the upper portion of the vertical leg 6 are provided at [2 the continuous packing means as well as the rollers shown at I3 which are protected both by the damming wall 8 and the packing means l2.

The upward inclination e of the upper boundary'wall M of the bottom sluice is the same, of

course, in Figs. 1 and 2, and as seen from Fig. 3, it is approximately equal to the upward inclination ,6 of the lower boundary wall 4 of the upper sluice. As shown in Figs. 1 and 2, the upper end of the vertical leg 6 has been rounded off so as to constitute a good guide for the overflow.

In Fig. 3 is clearly shown the box-like design of the upwardly inclined leg I of the bottom sluice, and from this figure is also seen how the breadth of the leg I as Well as the breadth of the trapezoidal upper sluice may be reduced toward the ends of the weir plant, whereas the height of the tension boom 2 of the upper sluice increases toward the ends of the weir plant. At l5 in Figs. 1, 2 and 3 is shown the bottom packing means.

In the modification shown in Figs. 4 and 5, the bottom sluice, which as in Figs. 1 and 2 is of angular transverse section or V-shape, has a single wall only, and its vertical leg i6 forms an acute angle 6' with the upwardly inclined leg H, which consists of a single main cross bar or beam Hi. The vertical supporting wall of the bottom sluice is formed solely by the damming wall l9. At is shown the tension boom of the main cross bar or beam I8. The V-shaped frame portion lies on the air side within the space bounded by the damming wall l9 and the upwardly inclined main cross bar or beam I8 so that the joint between the leg i1 and the vertical leg I6 can be lowered to the bottom beam shown at 22. At 23 are shown the abutting rollers, while 2% denotes the packing means. At 25 are indicated air-holes in the web of the upwardly inclined leg ill.

The design of the upper sluice which in Fig. 4 is shown in its operative or damming position and in Fig. 5 in its immersed or housed position, is substantially the same as that shown in Figs. 1 and 2. At 26 is shown the compression boom, which also in this embodiment constitutes the damming wall. 21 is the tension boom, while 28 and 29 are the web portions, the upper web portion, if desired, constituting the weir back. At 36 are shown transverse frame members for reinforcing or stiffening the trapezoidal supporting body.

Finally, in the embodiment of the invention shown in Figs. 6, '7 and 8, it is the bottom sluice which is of trapezoidal transverse section, whereas the upper sluice is of angular or hook-shaped transverse section.

In the bottom sluice there is shown at 3| the damming wall, whereas 32 denotes the tension boom. Within the box-shaped supporting structure lie the frame-members indicated at 33. At 34 is shown the connecting web.

The V-shaped upper sluice which is movable from its operative or damming position shown in Fig. 6 to its inoperative or immersed position shown in Fig. '7, comprises the vertical leg shown at and the downwardly inclined leg shown at 36, the two legs forming with each other an acute angle 6. According to Figs. 6 and 7, the two legs have a double-wall formation, while according to Fig. 8, they have a single-wall formation. The portion marked 3'! constitutes the weir-back. At 38 is shown the damming wall of the upper sluice, while at 39 is shown the tension boom thereof. At 59 are shown the abutment rollers, while 4! designates the packing means.

The inclination of the upper boundary of the bottom sluice indicated at 42 is practically similar to that of the lower boundary .3 of the downwardly inclined leg of the upper sluice, as clearly shown in Figs. 6 and '7. At 44 in Fig. '7 are indicated air-holes.

The letter M in Fig. 6 denotes the height of the weir-back 39, whereas the letter H in Fig. '7 denotes the distance of the axes of the abutment rollers from the sole of the weir. At 45 and 46 are respectively shown or indicated the corresponding slopes of the upper and bottom sluice.

The upper sluices are suspended in well-known manner from hoisting devices and their abutment in the horizontal direction is also obtained in well-known manner by means of rollers guided by rails, which are placed in suitable niches of the piers.

While in the double-sluice weir-plant shown in Figs. 1-5, the sluice of angular cross-section having a single main cross bar or beam only constitutes the bottom sluice, in the embodiment shown in Figs. 6-8 the sluice of angular cross-section having only a single main cross bar or beam constitutes the upper sluice of the weir.
